Found mainly in the Caribbean islands, it is also in Guyana (where it is called the ball-of-fire pepper), the Maldives Islands (where it is called mirus) and West Africa. It is named for its resemblance to a Tam o’ Shanter hat. Most Scotch bonnets have a heat rating of 100,000–350,000 Scoville units. For comparison, most jalapeño peppers have a heat rating of 2,500 to 8,000 on the Scoville scale. However there are completely sweet varieties of Scotch bonnet grown on some of the Caribbean islands, called cachucha peppers.  These peppers are used to flavour many different dishes and cuisines worldwide and are often used in hot sauces and condiments.
